ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 667, 33, dated February5, 1901 Application filed February 7, 1900. derial No. 4,365. (Nomodel.)

To atZZ whom, it may concern.-

Be it known that I, JULIUS A. PERKINS, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented an Improvement in Roller-Bearings, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.The invention herein to be described is illustrated in a bearingcontaining a fixed journal or shaft and a rotatable box, the object ofthe invention being not only to overcome friction between the journaland box, but also to overcome end-thrust friction; but it will beunderstood that my invention is equally applicable to a constructionwherein the journal or shaft rotates and the box is non-rotative.

Figure 1 shows a journal or shaft in elevation surrounded by a boxrepresented in section, the end-thrust means being also in sec-' tion.Fig. 2 shows detached one of the cagecontrolling surfaces located withinthe inner ends of the box and surrounding the journal. Fig. 3 shows alocking-washer detached, and Fig. 4 shows the threaded-ring forming oneside of the track detached.

In the drawings, A represents a journal or shaft which may be fixed inany suitable fork, and thus become a wheel-journal, and B may beconsidered as a surrounding rotatable box. The journal is shown asprovided with a right-hand thread Ct and a left-hand thread a, thejournal presenting an unthreaded part a between said threads, the endsof the journal being reduced in diameter at a a The box B has a centralrib b and shoulders 1) b the latter serving to support rings 11 b faced,preferably, with antifriction-washers b 19 preferably of vulcanite, theends of the box being closed by head-plates 5 b represented as screwedinto said box and having central holes surrounding the journal, saidheads at their inner faces sustaining rings b b which surround thejournal and contain felt or dust washers I) I), said rings supportingantifriction-washers c c. The antifriction-washers constituteantiwearing-faces forthe rings 19 b and 5 b they constitutingcage-controllers, with which may act to position at suitable intervals,as the necessity of the bearing may require, rigid cages d cl,containing non-rotating roller-alining means, shown as spindles dsustained in the end walls of said cages and surrounded by bearing-rollers d chambered at their opposite ends and receiving balls dwhich are inter posed between said rollersand said spindles and betweensaid rollers and said cages to prevent the contact of the rollers witheither the spindles or cages, said cages having always a certain amountof end play between said washers and running at times between and out ofcontact with said washers.

The rib b serves to support an end-thrust track, composed, asrepresented, of a collar 6, extended through the central opening of saidrib and receiving upon its threaded end a ring 6', the flange of thecollar and one face of the ring constituting a raceway for antifrictionend-thrust devices, which may be a series of balls, as e 6 mounted inannular grooves made in end-thrustplates 6 e surrounding the shaftandheld in place thereon in suitable manner, said plates, as shown,

being held in place on the screw-threaded portions 0. a, the adjustmentof said plates insuring the proper contact of the end-thrust means withthe tracks referred to. The plates may be held in their adjustedposition bysuitable locking-plates f, (shown detached in Fig. 3,) eachhaving a suitable lugf to enter a spline in the journal A, or viceversa. Each end-thrust plate has one or more holes 2 to receive aspanner by which to rotate them.

The locking-plates are acted upon and held in place in contact with theplates 6 c to lock them in adjusted position by lockingnuts g g.

Having described my invention, what claim as new, and desire to secureby Letters Patent, is-

1. A journal, a surrounding box, rollerbearings interposed between saidbox and journal at the ends of the box, and adjustable end-thrust meanslocated between said roller- 3. A box, an internal rib carried by saidbox and presenting a track, a journal, adj ustableplates mountedthereon, and a series of balls interposed between each of said platesand said track.

4. A journal provided with right and left hand screw-threads, platesmounted thereon, a box having an internal rib, a track on said ribpresenting two faces, and two series of balls one between each of saidplates and said track.

5. Ajournal, asurrounding box, rigid cages interposed between saidjournal and said box at the ends thereof, said cages containingnon-rotating roller-alining means, a series of bearing-rollers chamberedat their ends, and balls located in said chambers and surrounding saidalining means to prevent the contact of said rollers with said aliningmeans and said cages, ant-ifriction-washers located at the opposite endsof said cages and located at a distance apart in excess of the length ofsaid cages to thereby enable said cages to run at times without rubbingcontact with said washers, and end thrust means including antifriotionmeans and a track occupying a position between the said cages.

6. A box and a journal, combined with a rib and a two-part trackdetachably applied to said rib, and plates having antifriction means tocontact with said track.

7. A box having an internal rib, combined with a two-part track appliedto and covering said rib, the two parts of said track being connected bya screw-thread.

8. In a roller-bearing, a box, a track located between the ends of thebox, plates contain ing antifriction means, and means to adjust saidplates with relation to said track and hold the said plates in adjustedposition;

9. In a roller-bearing, a box, a revoluble cage containingbearing-rollers, and traveling cage-controllers located at opposite endsof said cage, said controllers being of different diameters onecooperating with the outer side of one end of the cage near itsperiphery, the other acting against the outer side of the opposite endof the cage near its inner edge.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JULIUS A. PERKINS.
